Pitot tubes get really hot when heating is on. I've seen them glowing red-hot. If you left the cover on, it would probably melt/burn off.

Blocked static ports are a bit more tricky. You wouldn't notice until after you start to climb. Only then would you see a decrease in airspeed and no change in altitude.
